Importance of Sandhaniya Dravya in Ayurveda

Sandhaniya Dravya, as per Ayurveda, refers to a specialized group of medicinal substances that aid in the healing and repair of tissues, fractures, wounds, and other structural injuries. The Sanskrit word ‘Sandhana’ translates to joining or uniting, signifying the primary role of these herbs in facilitating tissue regeneration and promoting faster recovery. These herbs are extensively used in Vrana Ropana (wound healing), Asthi Sandhana (bone repair), and Twak Vikaras (skin ailments).

The concept of Sandhaniya Dravya is deeply rooted in Rasayana (rejuvenation therapy) and Shalya Tantra (surgical management), where their role in enhancing cellular regeneration and restoring structural integrity is well acknowledged. According to Acharya Sushruta, Sandhaniya herbs play a significant role in post-operative recovery, fracture healing, and even in chronic non-healing ulcers. Their mechanism of action is based on their ability to balance the doshas, nourish dhatus, and facilitate metabolic processes essential for repair and regrowth.

Dosha-Dhatu Physiology of Sandhaniya Dravya

The effect of Sandhaniya Dravya on doshas and dhatus determines their efficacy in healing processes.

1. Effect on Doshas:

• Vata Dosha: Sandhaniya herbs pacify excessive Vata, which is responsible for tissue degeneration, dryness, and delayed healing.

• Pitta Dosha: These herbs cool excessive Pitta, reducing inflammation and preventing infection in wounds and fractures.

• Kapha Dosha: They regulate Kapha to prevent excessive fibrosis or unwanted tissue overgrowth while maintaining necessary hydration and lubrication.

2. Impact on Dhatus (Tissues):

• Rasa Dhatu (Plasma & Fluids): Enhances hydration and promotes initial wound healing.

• Rakta Dhatu (Blood): Boosts circulation and oxygenation, accelerating tissue repair.

• Mamsa Dhatu (Muscle Tissue): Supports muscle regeneration and prevents atrophy.

• Meda Dhatu (Fat Tissue): Helps in filling tissue gaps in wound healing.

• Asthi Dhatu (Bone Tissue): Promotes faster fracture healing and strengthens bones.

• Majja Dhatu (Nervous & Bone Marrow Tissue): Supports nerve regeneration and marrow formation.

• Shukra Dhatu (Reproductive Tissue): Enhances overall vitality and cellular longevity.

Pharmacological Aspects of Sandhaniya Dravya

Sandhaniya herbs function through various pharmacological mechanisms, promoting wound healing and tissue repair:

1. Vrana Ropana (Wound Healing): Enhances granulation tissue formation and epithelialization.

2. Asthi Sandhana (Bone Healing): Aids in calcium deposition and bone mineralization.

3. Shotha Hara (Anti-inflammatory): Reduces swelling and pain associated with injuries.

4. Raktha Stambhana (Hemostatic): Controls excessive bleeding from wounds.

5. Pitta Shamaka (Cooling & Soothing): Reduces inflammation, redness, and burning sensation in wounds.
